Well, technically, your out of luck, because your files are way out of date of the current builds of eqemu. I'm not sure you will be able to find a DR that is compatiable with your current client(Let alone, finding a database compatible) The only thing I can think of is to patch to live, then head to
http://scorpious2k.2ya.com/, click on the were running dr6 box at top, and download the patch, which will backpatch you to 5.7. One thing though, even on DSL, be prepared for a huge download everquest+all expansions = around 3gb(good god when will they stop? =p) Make sure in the everquest patcher, you click advanced, and click all expansions.
If that doesn't work, you'll probably have to wait till the post OOW client is more stable with eqemu.
